A film sticking system is known as a roll-to-panel (RTP) system. For example, Japanese Patent Publication No. 5140788 (Patent Document 1) discloses an RTP system for attaching a polarizing film to a liquid crystal display panel.

In the system disclosed in Patent Literature 1, the liquid crystal display panel is conveyed to the sticking means by the first liquid crystal panel conveying means, and sent out from the sticking means by the second liquid crystal panel conveying means. The sticking means includes an upper sticking roller and a lower driving roller. The first liquid crystal panel transport means operates to feed the liquid crystal display panel between the upper sticking roller and the lower drive roller of the sticking means. The 2nd liquid crystal panel conveyance means receives the liquid crystal display panel to which the sheet piece of the polarizing film was stuck together from the sticking means, and conveys it downstream.

In Patent Literature 1, as the liquid crystal panel conveying means, a configuration specifically comprising a conveying roller is shown, but there is also reference to a configuration having an adsorption plate or the like.

Japanese Patent Publication No. 5911035 (Patent Document 2) discloses a method of bonding an optical film to an optical display panel of a relatively small size such as a smart phone or a small tablet. According to the method described in Patent Literature 2, a plurality of optical display cells are arranged vertically and horizontally on a substrate to form a cell assembly motherboard, and after bonding an optical film sheet to the optical display cells on the cell assembly motherboard, the optical A film sheet is cut to a size corresponding to the individual optical cells. This optical film sheet is supplied in the form of an optical film laminate roll obtained by winding a continuous web-shaped optical film laminate in a roll shape in which a carrier film was bonded to an optical film having a polarizer layer via an adhesive material layer. On the optical film layered product, at predetermined intervals in the longitudinal direction, cuts are made in the width direction in the optical film and the pressure-sensitive adhesive layer, and the above-described optical film sheet is formed between two adjacent incisions in the longitudinal direction. In the bonding position, the optical film sheet is peeled off from the carrier film together with the pressure-sensitive adhesive layer, and bonded to the optical display cell on the cell assembly mother board.

As described in Patent Literature 1, a conventional RTP system is typically applied to sticking a film to a panel with relatively high rigidity, such as a liquid crystal display panel having glass substrates on both sides. However, there are other fields of film sticking where the technology of the RTP system can be applied and the advantages of the RTP system such as improvement in production efficiency can be utilized by the application. For example, there is a use in which a resin film such as a polarizing film is attached to a shaping panel made of a 1/4 retardation film cut into a predetermined shape and a predetermined size. In this case, the 1/4 retardation film may be bonded to the polarizing film as a laminate with the 1/2 retardation film. In addition, a film laminate in which a brightness enhancing film is bonded to a polarizing film is also commonly used, and in the production of such a film laminate, one of the polarizing film and the brightness enhancing film is used as a shaping panel formed in a predetermined shape and predetermined dimensions. , It is thought that it will be advantageous from a viewpoint of productivity improvement if the other of a polarizing film and a brightness improving film can be bonded to this shape panel by an RTP system.

In addition, in the manufacture of organic EL display devices, which have been remarkably popular in recent years, organic EL (Organic LED, commonly referred to as "OLED") display panels have a thin film transistor (TFT) layer and a light emitting layer of organic material formed on a glass substrate. Then, a top surface protective film in the form of a resin film is bonded on the light emitting layer. Then, the glass substrate is peeled off, and the lower surface protective film on the resin film is bonded to the TFT layer exposed as a result of the peeling. In this case as well, it is advantageous from the viewpoint of improving productivity to apply the RTP system to the step of bonding the lower surface protective film, which is a resin film, to the laminate composed of the TFT layer, the light emitting layer, and the upper surface protective film.

However, in any of the cases described above, the panel to which the resin film is bonded is flexible, and in the structure using the transport roller described in Patent Literature 1, the flexible panel is placed between the bonding rollers without causing problems such as misalignment. It is not possible to perform bonding by passing through. Patent Literature 2 discloses a configuration in which a cell assembly motherboard is placed on a suction holding plate for bonding, and the cell assembly motherboard is passed through a bonding station while being held by a suction force. If the structure shown in this patent document 2 is adopted, it is thought that it will be possible to stick the resin film to the flexible panel.

However, the RTP system disclosed in Patent Literature 2 transfers a suction holding disc for bonding on which a cell assembly mother board is mounted, from the first surface inspection station disposed upstream of the bonding station to the bonding station, and transfers it. It is comprised so that the suction holding board for bonding on which this completed cell assembly mother board was mounted is further transferred to the 2nd surface inspection station arrange|positioned downstream from the bonding station. For this reason, the suction holding board for bonding has to move along a long conveyance path, and it is necessary to form a complicated and expensive suction mechanism for applying a suction force to the suction holding plate for bonding over the entire length of the long conveyance path. . In addition, in the RTP system described in Patent Literature 2, since the distance of the transport path along which the suction holding disc for bonding is moved is long, the bonded cell aggregate mother board is transferred to another transfer disc disposed on the downstream side, and the empty suction for bonding Since the holding plate cannot be returned to the upstream side on the same path, it is necessary to form a return path for another empty suction holding plate, and a wide installation space for the bonding device is required.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to drawings. 1 is a side view schematically showing the entirety of a resin film sticking system according to an embodiment of the present invention for sticking a resin film on a shape panel. Although this embodiment is a specific example in the case of using an optical film as a resin film, the resin film in this invention is not limited to the optical film provided with the optical characteristic, The film formed by other resin materials is also can include

The resin film sticking system 1 shown in FIG. 1 uses the roll 10 of the long strip-shaped resin film layered product 11. In this embodiment, as shown in FIG. 2 , the resin film laminate 11 includes a long strip-shaped carrier film 11a and an optical film laminated on the carrier film 11a via an adhesive layer 11b. (11c). The carrier film 11a can be formed of, for example, a resin material such as PET. The widthwise dimension of the resin film layered product 11 corresponds to the widthwise dimension or longitudinal dimension of the shaping panel to which the sheet of the optical film 11c is attached, as will be described later by the resin film sticking system of the present embodiment. It is a predetermined size.

As the optical film 11c, a polarizing film is typically used, but a resin film having other optical characteristics such as a 1/4 wavelength or 1/2 wavelength retardation film or a luminance enhancing film can also be used, for example. . When using a polarizing film as the optical film 11c, it is preferable to orientate the absorption axis of the polarizing film in the longitudinal direction of the resin film layered product 11. The adhesive force of the pressure-sensitive adhesive layer 11b is adjusted such that the adhesive force to the carrier film 11a is smaller than the adhesive force to the optical film. As described above, the resin film in the present invention includes films made of resin materials other than optical films. Examples of resin films other than such optical films include polarizing films and protective films bonded to other films. , a protective film commonly called a lower surface protective film, which is bonded to the TFT layer of an organic EL display panel, and the like.

The resin film sticking system 1 is equipped with the roll support part 20 and the sticking station 30. The roll 10 of the resin film laminate 11 is supported by a support shaft 21 formed in the roll support 20 so as to be able to rotate freely. The shaping station 30 is provided with a shaping panel conveying mechanism 40 for conveying the rectangular shaping panel 31 having a long side dimension and a short side dimension to the gluing part 32 . In the sticking station 30, an sticking roller mechanism 34 having an sticking roller 33 is provided in the sticking part 32, and a wedge-shaped peeling member 35 is provided at a position close to the sticking roller mechanism 34. ) is placed.

The resin film layered body 11 drawn out from the roll 10 supported so as to rotate freely on the support shaft 21 passes through the incision forming part 22 and through the dancer roller mechanism 23 Guide rolls 24 and 25 guide the release member 35 to the disposed position.

The cutting portion 22 is provided with a cutting edge 22a and a pedestal 22b disposed to face the cutting edge 22a with the resin film laminate 11 fed from the roll 10 interposed therebetween. do. The incision formation portion 22 has a depth of incision extending from the optical film 11c side to the interface between the pressure-sensitive adhesive layer 11b and the carrier film 11a in the width direction with respect to the resin film laminate 11 ( 11e). Formation of this incision 11e is performed while stopping the transfer of the resin film layered body 11 in the incision formation part 22 . That is, the transfer of the resin film laminate 11 is intermittently stopped in the incision forming portion 22, and the incision is performed in the stopped state. As a result, in the resin film laminate 11, a plurality of incisions ( 11e) are formed at predetermined intervals in the longitudinal direction of the laminate 11. The predetermined spacing of the incisions 11e in the width direction formed in the resin film laminate 11 is a predetermined width corresponding to the short side dimension of the shaping panel 31 of the shaping panel 11. It is assumed that it corresponds to the long side dimension of (31). As a result of this incision 11e, in the resin film layered product 11, as shown in Fig. 2, between the two adjacent incisions 11e in the longitudinal direction, the optical film 11c and the pressure-sensitive adhesive layer 11b are formed. A rectangular-shaped sheet with a pressure-sensitive adhesive layer 11d is formed.

As shown in FIGS. 1 and 2 , the resin film laminate 11 guided to the position of the peeling member 35 is folded back at an acute angle at the leading edge of the peeling member 35 . At this time, the rectangular film sheet 11d with an adhesive layer formed on the resin film layered product 11 and containing the optical film 11c and the adhesive layer 11b is peeled off from the carrier film 11a and attached. It is guided to the lower side of the roller 33. The carrier film 11a from which the film sheet 11d with an adhesive layer was peeled off is guided by the guide roll 26 and wound up by the take-up drive shaft 27 . The take-up drive shaft 27 is driven at a predetermined speed, and the feed of the resin film layered product 11 is determined by this take-up speed. On the other hand, since the resin film laminate 11 is intermittently stopped in the incision forming portion 22, a conveyance speed difference is generated. The dancer roller mechanism 23 is formed to compensate for this transfer speed difference.

As shown in FIGS. 1 and 2 , the shaping panel conveying mechanism 40 includes a suction holding member 41 , and the shaping panel 31 is suction-held on the upper surface of the suction holding member 41 . In the direction indicated by the arrow A in FIG. 1, it is conveyed through the sticking part 32. The transfer of the shaping panel 31 by the suction holding member 41 is synchronized with the transfer of the resin film laminate 11, and the front end of the film sheet 11d with an adhesive layer peeled off by the peeling member 35 is It is controlled so that it may be matched with respect to the front end of the shaping panel 31 conveyed to the sticking part 32. In the sticking unit 32, the sticking roller mechanism 34 operates, and the sticking roller 33 presses the film sheet 11d with an adhesive layer onto the shaping panel 31 on the adsorption holding member 41 and sticks it. carry out

A shaping panel transport line 50 is disposed on the upstream side as viewed in the transport direction of the suction holding member 41, and the shaping panel 31 is brought closer to the shaping panel mounting position 42 by this transport line 50. are transported to the location Above the standard panel mounting location 42, the standard panel 31 transported by the standard panel transfer line 50 to a position close to the standard panel mounting location 42 is transferred to the standard panel mounting location 42. A shaping panel mounting mechanism 60 for transferring onto the adsorption holding member 41 positioned is formed. In addition, in the sticking station 30, a shaping panel with a resin film sheet take-out position 43 for taking out the shaping panel 31a with a resin film sheet on which the sticking of the film sheet 11d with an adhesive layer has been completed is provided, Adjacent to the downstream side of the take-out position 43, a molded panel delivery line 51 with a resin film sheet is disposed. Above this delivery line 51, there is a panel transfer mechanism for transferring the shaping panel 31a with a resin film sheet to the shaping panel with a resin film sheet delivery line 51 from the shaping panel with a resin film sheet take-out position 43. (70) is placed.

4 and 5 show details of the shaping panel conveying mechanism 40 . 4 is a side view of the shaping panel transfer mechanism 40, and FIG. 5 is a cross-sectional view seen in the direction of arrow V-V in FIG. As shown in the drawing, the shaping panel conveying mechanism 40 has two guide rails 45 arranged in parallel on a base 44 in a direction indicated by an arrow A in FIG. 1 . The suction holding member 41 is in the form of a rectangular flat plate, and is provided with four support legs 46 extending vertically downward. The lower end of the support angle 46 is coupled to the lower support plate 47 . On the lower surface of the lower support plate 47, a sliding member 48 is fixed to the guide rail 45 on the base 44 and slidingly moves along the guide rail 45. The sliding members 48 are formed in a total of four pieces, two at a time, for each pair of guide rails 45 .

The shaping panel transport mechanism 40 includes a suction holding member driving mechanism 80 . The suction holding member drive mechanism 80 is disposed between a pair of guide rails 45 and includes a drive screw 81 extending parallel to the guide rails 45 . The drive screw 81 is supported on a base 44 so that it can rotate freely around its longitudinal axis. A nut member 82 screwed to the drive screw 81 is fixed to the lower support plate 47 . The nut member 82 and the drive screw 81 form a ball screw mechanism that engages with each other with low friction through a large number of balls arranged in the nut member 82 . The end of the drive screw 81 is coupled to the servomotor 84 via the speed reducer 83, and is rotationally driven by the servomotor 84 reversibly. As a result of this reversible rotational drive, the suction holding member 41 is driven in the return direction opposite to the transfer direction indicated by the arrow A. That is, as a result of the drive screw 81 of the suction holding member drive mechanism 80 being reversibly rotationally driven in the forward rotation direction and the reverse rotation direction, the suction holding member 41 is moved to the front panel mounting position (42 ) through the sticking station 30 to the output position 43 of the shaped panel with the resin film sheet is moved in the direction of the arrow A in FIG. 1 . Then, the adsorption holding member 41 is moved along the return path in the return direction opposite to the arrow A, with the shaping panel take-out position 43 with the resin film sheet as a turning end. The return route is the same route as the outbound route, and the suction holding member 41 passes through the sticking station 30 and is returned to the fixed panel mounting position 42, which is the starting end on the outbound route side.

The suction holding member 41 is in the form of a suction plate that adsorbs the shaping panel 31 transferred on the shaping holding member 41 by the shaping panel mounting mechanism 60 by a suction force and holds it so as not to be displaced. . The adsorption holding member 41 constituted by the adsorption plate is preferably sized to cover the entire surface of the shaping panel 31 to be adsorbed and held. An embodiment of the suction holding member 41 is shown in FIG. 6(a)(b). As shown in FIG. 6(a), the suction holding member 41 arranges a plurality of rectangular suction plates 41a side by side in a rectangular frame member 41c, and is placed between two adjacent suction plates 41a. It is a structure in which the partition member 41b was formed. The frame member 41c is integrally formed with the bottom plate 41d, and the suction port 41e is formed in the bottom plate 41d at a position corresponding to each of the plurality of suction plate pieces 41a. Each suction port 41e is connected to a collecting pipe 41h via a branch pipe 41g having a valve 41f, and the collecting pipe 41h is connected to a suction source P such as a vacuum pump. .

By forming the branch pipe 41g having the partition member 41b and the valve 41f, the opening and closing of the valve 41f is appropriately controlled, and only by selecting the suction plate 41a on which the suction force acts, the frame member 41c is removed. It is possible to reliably adsorb and hold not only the large shaping panel 31 corresponding to the size but also the shaping panel 31 of medium size and small size. However, the suction plate 41a may be configured as a single piece having a size corresponding to the size of the frame member 41c. The suction plate 41a can be formed of a porous material. Examples of porous materials include porous ceramics or porous films of high molecular weight resins. As an example of the porous ceramics that can be used in the present embodiment, there is NPP-3D micro-diameter porous ceramics manufactured by Nippon Tungsten Co., Ltd. Moreover, as a porous resin film, there exists a high molecular weight polyethylene porous film "Sunmap LC-T" by Nitto Denko Corporation. In addition, in this embodiment, a perforated plate having fine through-holes formed on the entire surface can also be used. In the case of using a perforated plate, the diameter of the through hole is preferably 3 mm or less, and the interval between the holes is preferably 30 mm or less. If the diameter of the hole is larger than 3 mm, there is a possibility that traces of the hole remain on the shaping panel 31 held by the suction holding member 41 . In addition, when the gap between the holes is too large, there is a risk that sufficient suction force cannot be obtained and the retention becomes uncertain.

Referring to Fig. 4, a branch pipe 41g and a collecting pipe 41h are shown below the suction holding member 41. The shaping panel conveying mechanism 40 further includes a hose-embedded flexible belt 49 for applying suction negative pressure to the collecting tube 41h. The hose-embedded flexible belt 49 has a structure in which a hollow hose 49b is embedded in a belt substrate 49a made of a flexible material such as rubber, and the belt substrate 49a has one end attached to the base 44, The other end is fixed to the lower support plate 47 which supports the suction holding member 41, respectively. The collecting pipe 41h communicating with the suction plate 41a via the branch pipe 41g and the suction port 41e is the end of the side fixed to the lower support plate 47 of the hose-embedded flexible belt 49, that is, the movable side end , connected to the end of the hollow hose 49b embedded in the hose-embedded flexible belt 49. On the other hand, the end of the side fixed to the base 44 of the flexible belt 49 with a built-in hose, that is, the end of the fixed side is connected to the suction source P by a connecting hose 41j. In the shaping panel mounting position 42 shown in FIG. 4 , the belt base material 49a of the hose-embedded flexible belt 49 is in a folded state at a substantially central position in the longitudinal direction.

With this configuration using the hose-embedded flexible belt 49, the lower support plate 47 supporting the suction holding member 41 moves in the direction of arrow A from the shaping panel mounting position 42 shown by the solid line in FIG. When this happens, the folded back position of the belt base material 49a of the hose-embedded flexible belt 49 is gradually shifted, and the lower support plate 47 supporting the suction holding member 41 is easily moved to the lower support plate 47. follow the movement of Then, suction negative pressure is supplied to the lower surface of the suction plate 41a of the suction holding member 41 over the entire area during outward movement where the shaping panel 31 is mounted on the upper surface of the suction holding member 41 .

Next, referring to Figs. 7 and 8, the shaping panel mounting mechanism 60 will be described. The shaping panel mounting mechanism 60 in this embodiment has a horizontal movement mechanism 60a and a vertical movement mechanism 60b.

The horizontal moving mechanism 60a includes a horizontal frame 62 supported by supports 61 . The horizontal frame 62 is arranged to extend in the direction of arrow A in Fig. 4, and has an upper wall 62a and a lower wall 62b. Between the upper wall 62a and the lower wall 62b, a drive screw 63 extending in the longitudinal direction with respect to the horizontal frame 62 is disposed, and the drive screw 63 has both ends in the longitudinal direction, 1 It is supported on the horizontal frame 62 by a pair of bearings 62d and 62e so as to be able to freely rotate around its axis. One end of the driving screw 63 slightly extends from the bearing 62e and is coupled to the servo motor 62g via a reduction gear 62f. The servo motor 62g is connected to the power supply E. As shown in FIG. 8, on the upper surface of the upper wall 62a, a pair of guide rails 62c are fixedly disposed, and in a portion between the pair of guide rails 62c, the upper wall 62a ), a slot 62h extending in the longitudinal direction is formed.

A support plate 64 for the vertical movement mechanism 60b is formed, and on the lower surface of the support plate 64, a sliding member slidably fitted to the guide rail 62c formed on the upper wall 62a of the horizontal frame 62. (64a) is fixed. Moreover, on the lower surface of the support plate 64, the nut member 64b which passes through the slot 62h of the horizontal frame 62 and engages the drive screw 63 is fixed. As in the case of the nut member 82 and the drive screw 81, the drive screw 63 and the nut member 64b form a ball screw mechanism. With this configuration, the support plate 64 moves along the upper wall 62a of the horizontal frame 62 in the longitudinal direction of the horizontal frame 62 with rotation of the servomotor 62g. The servomotor 62g is capable of normal and reverse rotation, drives the support plate 64 in the right direction, for example, in FIG. 7 by rotation in the forward rotation direction, and rotates the support plate 64 by rotation in the reverse rotation direction. For example, in FIG. 7, it is driven in the left direction. The length of the slot 62h formed in the upper wall 62a of the horizontal frame 62 is such that the shaping panel 31 is moved from the shaping panel transfer line 50 to the shaping panel loading position for the transfer of the shaping panel 31. It is determined so as to correspond to the distance required for conveyance to the suction holding member 41 in (42).

A flexible belt 65 with a built-in wire/hose is provided in the horizontal movement mechanism 60a. Like the hose-embedded flexible belt 49, the wire/hose built-in flexible belt 65 has a structure in which an electric wire and a hollow hose are embedded in a belt base material 65a made of a flexible material such as rubber. 65a, one end constituting a fixed end is attached to the lower wall 62b of the horizontal frame 62, and the other end constituting a movable end is attached to the support plate 64 of the vertical movement mechanism 60b, respectively. At the fixed end of the flexible belt 65 with built-in electric wire/hose, the electric wire is connected to the power source E and the hose is connected to the suction source P, respectively. Therefore, the position of the support plate 64 of the vertical movement mechanism 60b moving in the longitudinal direction of the horizontal frame 62 in accordance with the operation of the servo motor 62g is provided by the flexible belt 65 with a built-in electric wire/hose. , power and suction negative pressure are supplied.

The vertical movement mechanism 60b includes a movable frame 66 fixed to a support plate 64 . In the movable frame 66, a vertical driving screw 66a is arranged so as to extend in the vertical direction, and is rotatably supported by bearings at the upper and lower ends. The upper end of the drive screw 66a is coupled to a servo motor 66b, and is reversibly driven by the servo motor 66b. A pair of guide rails 66c and a slot 66d are formed on the left wall of the movable frame 66 in Fig. 8, similarly to the case of the horizontal movement mechanism 60a. A nut member 66e is engaged with the drive screw 66a, and this nut member 66e protrudes leftward in FIG. 8 from a slot 66d formed in the side wall of the movable frame 66. The driving screw 66a and the nut member 66e form a ball screw mechanism.

A vertical movable member 67 for supporting the suction holding member is coupled to the nut member 66e, and a suction holding member 68 is attached to the lower end of the vertically movable member 67. The structure of the adsorption holding member 68 is the same as that of the adsorption holding member 41 shown in FIG. 6, and in the case of the adsorption holding member 68, the adsorption surface is disposed downward. The electric wire incorporated in the electric wire/hose built-in type flexible belt 65 is connected to the servomotor 66b by the connecting electric wire 66f at the fixed-side end of the electric wire/hose built-in type flexible belt 65, , the hose is connected to the suction holding member 68 through the vertically movable member 67 by the hose 66g for connection.

In the operation of the standard panel mounting mechanism 60, when the standard panel 31 is transported to a position adjacent to the standard panel mounting position 42 by the patterned panel transfer line 50, the standard panel mounting mechanism 60 The servomotor 66b formed in the vertical movement mechanism 60b of ) operates to rotationally drive the drive screw 66a in the forward rotation direction. Thereby, the vertically movable member 67 and the suction holding member 68 move downward, come into contact with the shaping panel 31 on the shaping panel conveyance line 50, and the suction negative pressure supplied to the shaping holding member 68 Thus, the shaping panel 31 is held by suction. In that state, the servomotor 66b is rotated in the reverse rotation direction, and the suction holding member 68 is raised. During the lifting process of the suction holding member 68 or when the lifting is completed, the servomotor 62g of the horizontal moving mechanism 60a rotates in the forward rotation direction to drive the drive screw 63 forward. and the adsorption holding member 68 of the vertical movement mechanism 60b is moved from the shaping panel transfer line 50 to a position above the shaping panel mounting position 42. During the movement of the suction holding member 68 to the upper position of the shaping panel mounting position 42, or when reaching the upper position of the shaping panel mounting position 42, the servo motor of the vertical movement mechanism 60b ( 66b) is operated in the forward rotation direction to initiate the lowering of the suction holding member 68 that adsorbs and holds the shaping panel 31 . When the suction holding member 68 reaches the upper position of the shaping panel mounting position 42, the servo motor of the horizontal moving mechanism 60a is stopped, and the shaping holding member 68 holds the shaping panel 31 It is lowered so as to come into contact with the adsorption holding member 41 at this shaping panel mounting position 42 .

Supply of suction negative pressure to the suction holding member 68 when the shaping panel 31 held on the shaping holding member 68 comes into contact with the shaping holding member 41 at the shaping panel mounting position 42 is cut off, and at the same time, the supply of negative suction pressure to the suction holding member 41 is started. As a result, the shaping panel 31 is in a state of being adsorbed and held by the shaping holding member 41 of the shaping panel transfer mechanism 40, and the transfer of the shaping panel 31 is completed. Next, while the servo motor 66b of the vertical movement mechanism 60b operates in the reverse rotation direction to raise the suction holding member 68 on which the shaping panel 31 is placed, the operation of the horizontal movement mechanism 60a to return the suction holding member 68 to the position above the end of the shaping panel transport line 50.

Since the panel transferring mechanism 70 for transferring the shaping panel 31a with a resin film sheet to the shaping panel delivery line 51 with a resin film sheet has the same configuration as the shaping panel mounting mechanism 60, detailed description thereof is omitted. .

Next, with reference to FIG. 9, the procedure of sticking 11 d of film sheets with an adhesive layer to the shaping panel 31 is demonstrated. In FIG. 9( a ), a suction holding member 41 adsorbing and holding the transferred shaping panel 31 on the upper surface at the shaping panel mounting position 42 is directed toward the affixing member 32 of the affixing station 30 Indicates the state of movement in the direction of the arrow. The resin film layered product 11 is a film with a pressure-sensitive adhesive layer formed on a carrier film 11a by inserting incisions 11e in the width direction between the optical film 11c and the pressure-sensitive adhesive layer 11b at predetermined intervals in the longitudinal direction. It has a seat 11d. This resin film laminate 11 is folded back at an acute angle around the edge of the peeling member 35, and the tip of the film sheet 11d with an adhesive layer located at the top is peeled off from the carrier film 11a, It protrudes forward from the leading edge of the peeling member 35. The transfer of the resin film layered product 11 is such that the front end of the film sheet 11d with an adhesive layer peeled from the carrier film 11a is transferred to the sticking portion 32, and the shaping panel on the suction holding member 41 ( 31) is synchronized with the conveyance of the suction holding member 41 so as to align with the front end in the conveyance direction.

The sticking operation|movement in the sticking part 32 is shown to FIG.9(b)(c)(d). As indicated by the arrow, the sticking roller 33 moves downward and presses the film sheet 11d with an adhesive layer peeled from the carrier film 11a on the upper surface of the shaping panel 31 . The front end of the film sheet 11d with the pressure-sensitive adhesive layer is aligned with the front end of the shaping panel 31, and the pressure-sensitive adhesive layer is overlapped with the shaping panel 31 in a state facing the shaping panel 31. The superimposed film sheet 11d with an adhesive layer and the shaping panel 31 are sandwiched between the suction holding member 41 and the sticking roller 33, and the film sheet 11d with an adhesive layer is held together by the adhesive layer 11b. It is adhered to the shaping panel (31). As shown in FIG. 9(d), this sticking operation progresses toward the rear end of the shaping panel 31 in the conveying direction as the suction holding member 41 is conveyed in the direction of the arrow, and the sticking is completed. After that, the shaping panel 31a with the resin film sheet to which the optical film has been attached is conveyed toward the take-out position 43, as shown in Fig. 9(e).

In the above, one embodiment of the present invention has been described with reference to the embodiments shown in the drawings, but the present invention is not limited to the details of the illustrated and described embodiments. Although the embodiment shown in the drawing relates to sticking of an optical film, as described above, the present invention is not limited to sticking of an optical film, and can be applied to sticking of other resin films.

In addition, the shaping panel is mounted on the suction holding member on one side of the affixing station, and the shaping panel with the resin film sheet to which the resin film is attached is taken out on the other side of the affixing station. In a state where the shaping panel to which the resin film has been attached is held on the suction holding member as it is, it may be returned to its original position through the sticking station and taken out from the original position. Alternatively, the mounting position of the shaping panel is set to a position on the exit side of the affixing station, and the suction holding member holding the mounted shaping panel is passed through the affixing station without performing an affixing operation, and then adsorbed and held It can also be set as the structure which reverses the conveyance of a member, makes it pass through an sticking station, and sticks. These configurations possible in the present invention may be appropriately selected according to the available space at the grounding point.
